Texas Instruments Inc. (TI) introduced a pair of 8/10-bit triple analog-to-digital converters (ADCs) providing up to 165 mega-samples per second (MSPS). Designed for business projectors, televisions and STBs, the TVP700x series of devices deliver a wide range of benefits, including improved jitter-reduction performance, higher image quality in video systems and the ability to support the increased bandwidth needed from PC and high definition (HD) video output.

"Both the TVP7000 and TVP7001 provide the video performance and quality our customers and the market demand in their products," said Frank Moizio, worldwide strategic marketing manager for DLP front projection at TI. "Both of these devices are fully compatible with current DLP Imaging ASIC products providing up to UXGA resolutions and 1080p analog HD support."

The TVP7000, featured on the DDP2000 DLP reference design, provides sampling rates up to 150MSPS and supports 1080p video inputs. The TVP7001 is available with the DDP3020 DLP reference design and delivers up to 165MSPS and increases PC graphics output to 1,600 x 1,200 at 60Hz ultra extended graphics array (UXGA) quality. The two devices also support a 10-bit mode up to 110MSPS allowing for superior video quality.

Both devices offer integrated phase-locked loops (PLL) for pixel clock generation. An output formatter provides complete support for RGB/YCbCr 4:4:4 and YCbCr 4:2:2, as well as dedicated Data Clock for easy latching of output data. The device also supports three digitizing channels with individual clamps, an 8-bit programmable gain amplifier, a 3:1 input multiplexer and automatic offset control for both YPbPr and RGB inputs.

The TVP7001 is available for sampling with volume production scheduled for December 2005, while the TVP7000 is already in production. Both devices are offered in a 100-pin Pb-Free PZP PowerPad HTQFP package. Evaluation modules are also available.
